SIMULATION AND FIELD MEASUREMENTS OF THE LONG-TERM RAIL SURFACE DAMAGE DUE TO PLASTICITY, WEAR AND SURFACE ROLLING CONTACT FATIGUE CRACKS IN A CURVE
Paper i proceeding, 2022

A methodology that simulates the long-term rail surface damage in a cross-section of a curve for a given traffic scenario is presented. The numerical model considers plastic deformation, wear, and initiation of rolling contact fatigue (RCF) surface cracks. The models and simulations are calibrated and validated, respectively, against field profile measurement data.

FE simulations

elastic-plastic contact

rolling contact fatigue

accumulated plastic deformation
